Message Submission

The University's message submission service is provided by smtp.ox.ac.uk .

The service can be accessed on either port 587/tcp (recommended) or 25/tcp. There are two types of access.

Authenticated

SMTP AUTH is available globally and offers GSSAPI, LOGIN and PLAIN authentication types. Use port 587 because many ISPs block outbound 25/tcp traffic. It is unlikely the network you are on will block port 587 but in the event that it does, use the University's central VPN service to tunnel back to the Oxford network so that you can connect to smtp.ox.ac.uk.
